    lib/reg_script: Add display support
    
    Add the ability to enable the display of the script:
    * Added REG_SCRIPT_COMMAND_DISPLAY to enable and disable display output
    * Added context values to manage display support
      * display_state - Updated by the command to enable or disable display
      * display_features - May be updated by step routine to control what
        the step displays for register and value
      * display_prefix - Prefix to display before register data
    * Added REG_SCRIPT_DISPLAY_ON and REG_SCRIPT_DISPLAY_OFF macros to
      control the display from the register script
    * Added REG_SCRIPT_DISPLAY_REGISTER and REG_SCRIPT_DISPLAY_VALUE as
      two features of the common display.  With these features enabled
      the following is output:
      * Write: <optional prefix> register <-- value
      * Read:  <optional prefix> register --> value
